Are We Having Fun Yet?

Some typos are such fun! The reference in the review of “Beyond the Helix, DNA and the Quest for Longevity” (Nov. 10 Book Review) to “an anti-aging regiment” conjures up the image of svelte, leotarded troops armed with dye guns for spraying gray hair and surgical Scotch tape for tucking up whatever sags. So much more fun than an anti-aging regimen.
